Phantom power

StarLeaf room systems offer phantom power through each of their XLR connectors for use by active microphones, such as the StarLeaf Microphone. The phantom power supply can be enabled or disabled for each XLR connector, using the Group Telepresence options in the StarLeaf Portal or through the web interface of a GTm. It is compatible with active microphones, which are designed for 48V phantom power. The specifications of the power supply are:

  • Output voltage when operational, no load: 45.3V +/- 4%
  • Output voltage when muted, no load: 35.3V +/- 4%
  • Power output source impedance: 1.975kOhms +/- 2%
